What could be more frightening than a slain enemy rising to fight again?
This Halloween tale (guest-starring Hitler himself) dares to answer the question!
This scary story from Quality's Military Comics #15 (1943) has a scientific, instead of supernatural, explanation.
Blue Tracer creator/writer/artist Fred Guardineer created and handled both sci-fi and mystical characters with equal enthusiasm, but he always seemed uncomfortable about doing war stories, unless they had a fantastical element.
Even this ongoing contribution to Military Comics (which was a fairly realistic war comic, except for Blackhawk), was about a fantastic torpedo-shaped vehicle that fought the Axis with super-science.
